    The SPIKE anchor is a patented, one-piece, tamper-proof vibration resistant anchor for use in concrete, block, brick or stone. Several head styles and anchor materials are available. The SPIKE anchor is formed with an "s" shaped configuration at the working end of the anchor to create an expansion mechanism. Since the anchor is pre-expanded, there is no secondary tightening operation required which greatly reduces the overall cost of an anchor installation. Box of 25 General Applications and Uses: Tamperproof Applicatinos, Exterior Applications, Cable Trays and Strut, Pipe Hanging, metal Track Attachments, Concrete Formwork. Suitable Base Materials: Normal-Weight Concrete, Structural Lighweight Concrete, and Grouted Concrete Masonry (CMU)
